The previous owner of my home replaced and added more windows. Unfortunately, many of them were not properly air sealed at the rough opening and, if I had to guess, maybe not well on the exterior sheathing side either. I'm not experiencing any signs of water intrusion or mold on the interior that I can see.
The windows are nearly all American Craftsman vinyl framed, LowE glass and installed into 6" deep walls (2 x 6 studs). There are three Anderson proper windows and an Anderson sliding glass door.
It's been very cold here in NJ and this amounts to many noticeable streams of cold air that emanate from around the interior window decorative trim that is installed around the drywall window opening on the inside wall.
There are unsealed gaps between the inside vinyl window frame and the wooden side jamb where the cold air also shoots through.
On the one hand, I'd love to figure out a way to get to the RO and pack in Rockwool bat and then seal over with Tescon Vana tape. However, I expect that's going to require me to rip apart the drywall.
On the other hand, I'm thinking the easier, but still effective for air infiltration stoppage would be to seal the gaps between the vinyl window frames and the inside jambs along with sealing the wall trim to both the side jambs and the drywall with a bead of Dynaflex 230. I realize this doesn't stop the cold air infiltration into the walls themselves and the associated cold/moisture sinking of the wall, but for an immediate comfort improvement, this seems the least expensive and deconstructive.
Any thoughts? |
